I just don't care?

So, I let my really close gay friends fuck on the mattress under my bed, bc my bed is just two mattresses put together, every time they come over. I don't mind it, they're my best friends and they're so chill and they don't really anywhere to go. They're quiet and I just turn my back and play on my phone and i didn't know if that made me weird or just a good friend 😂😂 I'm a very open minded person who doesn't care about that stuff and I love when people are happy with who they're with. I just wanted thoughts on it. Sorry this is weird.
